Kourtney Kardashian Shares First Pic of Her Adorable Son Reign!

The eldest Kardashian sister, 35, revealed her son Reign Aston Disick's face for the first time in this super-cute Instagram pic she posted on Thursday, in which he's clad in a plain white button-up onesie.

But one star apparently not that concerned with getting her pre-baby body back is Olivia Wilde -- though it's safe to say it's pretty perfect already. Olivia gave birth to her first child, Otis Alexander Sudeikis, last April.

"I am not in perfect shape," she recently claimed to Shape magazine. "In fact, I'm softer than I've ever been, including that unfortunate semester in high school when I simultaneously discovered Krispy Kreme and pot."
